Morphological variations of plicofollis species (Siluriformes: Ariidae) in Peninsular Malaysia: an insight into truss network Approach

Ariid catfishes, belong to family Ariidae is considered as one of the taxonomically problematic groups, which is still under review by fish taxonomist globally. Species level identification of some ariids often resulted in species misidentification because of their complex characters and very simila...
